Common name: Canary wrasse

General information

The Yellow Coris Wrasse, Halichoeres chrysus, is a vibrant and active fish that brings both color and dynamic behavior to the reef aquarium. It is known for its bright yellow coloration, which can vary in intensity depending on the fish's mood and environment. Juveniles often have black spots that may fade as they mature.

This species is part of the wrasse family, which is known for its members' interesting behaviors and diverse color patterns. The Yellow Coris Wrasse is also appreciated for its pest control abilities, as it actively hunts for small invertebrates, including pyramid snails and flatworms that can be harmful to corals.

Care

Yellow Coris Wrasses are hardy and adaptable, making them suitable for both novice and experienced aquarists. They require a well-established aquarium with a sandy substrate for burrowing and plenty of live rock for hiding and hunting. A tight-fitting lid is essential, as wrasses are known jumpers.

Their diet should include a variety of meaty foods such as frozen mysis shrimp, brine shrimp, and finely chopped seafood. They also appreciate live foods and will help control pest populations in the aquarium.

Reproduction

In the wild, Yellow Coris Wrasses are protogynous hermaphrodites, meaning they are born female and can change to male if the dominant male is absent. In the aquarium, breeding is less common, but with a group consisting of one male and several females, spawning may occur.

Habitat

Native to the Indo-Pacific region, Yellow Coris Wrasses are found in shallow, coral-rich areas and lagoons. They are often seen darting in and out of the reef structure in search of food. In the aquarium, they require similar conditions with plenty of live rock and a sandy bottom to mimic their natural habitat.
